26/**
27 * <b>StubFtpServer</b> is the top-level class for a "stub" implementation of an FTP Server,
28 * suitable for testing FTP client code or standing in for a live FTP server. It supports
29 * the main FTP commands by defining handlers for each of the corresponding low-level FTP
30 * server commands (e.g. RETR, DELE, LIST). These handlers implement the {@link CommandHandler}
31 * interface.
32 * <p/>
33 * <b>StubFtpServer</b> works out of the box with default command handlers that return
34 * success reply codes and empty data (for retrieved files, directory listings, etc.).
35 * The command handler for any command can be easily configured to return custom data
36 * or reply codes. Or it can be replaced with a custom {@link CommandHandler}
37 * implementation. This allows simulation of a complete range of both success and
38 * failure scenarios. The command handlers can also be interrogated to verify command
39 * invocation data such as command parameters and timestamps.
40 * <p/>
41 * <b>StubFtpServer</b> can be fully configured programmatically or within a Spring Framework
42 * ({@link http://www.springframework.org/}) or similar container.
43 * <p/>
44 * <h4>Starting the StubFtpServer</h4>
45 * Here is how to start the <b>StubFtpServer</b> with the default configuration.
46 * <pre><code>
47 * StubFtpServer stubFtpServer = new StubFtpServer();
48 * stubFtpServer.start();
49 * </code></pre>
50 * <p/>
51 * <h4>Retrieving Command Handlers</h4>
52 * You can retrieve the existing {@link CommandHandler} defined for an FTP server command
53 * by calling the {@link #getCommandHandler(String)} method, passing in the FTP server
54 * command name. For example:
55 * <pre><code>
56 * PwdCommandHandler pwdCommandHandler = (PwdCommandHandler) stubFtpServer.getCommandHandler("PWD");
57 * </code></pre>
58 * <p/>
59 * <h4>Replacing Command Handlers</h4>
60 * You can replace the existing {@link CommandHandler} defined for an FTP server command
61 * by calling the {@link #setCommandHandler(String, CommandHandler)} method, passing
62 * in the FTP server command name and {@link CommandHandler} instance. For example:
63 * <pre><code>
64 * PwdCommandHandler pwdCommandHandler = new PwdCommandHandler();
65 * pwdCommandHandler.setDirectory("some/dir");
66 * stubFtpServer.setCommandHandler("PWD", pwdCommandHandler);
67 * </code></pre>
68 * You can also replace multiple command handlers at once by using the {@link #setCommandHandlers(Map)}
69 * method. That is especially useful when configuring the server through the <b>Spring Framework</b>.
70 * <h4>FTP Command Reply Text ResourceBundle</h4>
71 * <p/>
72 * The default text asociated with each FTP command reply code is contained within the
73 * "ReplyText.properties" ResourceBundle file. You can customize these messages by providing a
74 * locale-specific ResourceBundle file on the CLASSPATH, according to the normal lookup rules of
75 * the ResourceBundle class (e.g., "ReplyText_de.properties"). Alternatively, you can
76 * completely replace the ResourceBundle file by calling the calling the
77 * {@link #setReplyTextBaseName(String)} method.
